Kind Code:
A1
Abstract:
The present invention suppresses the radiation of radio waves to under an antenna unit. This antenna unit is configured to be installed for use facing the window glass of a building, and comprises a plurality of array antennas. The plurality of array antennas each have a plurality of radiation elements, and at least one conductor positioned indoors for the plurality of radiation elements. When the effective wavelength at the operating frequency of the plurality of array antennas is λ, and an integer of 0 or greater is n, in a planar view of the antenna unit, the distance in the vertical direction from the center of an upper radiation element of the plurality of radiation elements to the upper edge of the conductor is (0.5+n)λ±0.22λ.
